Check-Manual von kube_pod_resources
|Kubernetes: Pod Resources|
|Distribution||Official part of Checkmk|
Moreover, on clusters and nodes the check monitors the number of allocatable pods, the pod capacity and the number of free pods available on the node/cluster. The number of free pods is equal to the number of allocatable pods minus the number of pending and running pods.
Upper levels for
CRIT can be defined for the time a pod is pending.
The duration a pod is pending is calculated based on the time checkmk has seen the pod, not on data
provided by the Kubernetes API. This means the pending phase duration is zero when the
monitoring first begins, even if there are pods, which have been pending for much longer. By
default, any time a pod spends pending is tolerated and the service remains
If a pod exceeds the tolerating time period, the pod name will be displayed next to the number of pods. If there are more than three pods exceeding the time limit, only the those three pods, which have been in the pending phase the longest will be shown.
The service goes
CRIT if the count of free pods is less than 10%/5% of the allocatable pods.
The levels for pending and free pods can be configured via the rule Kubernetes pod resources.
The pod names of unknown pods are displayed in similar fashion as for the pending pods. However, pod names are not displayed based on how long they have been unknown.
The check requires that the special agent kube is configured.
